Case presentation: nephrolithiasis in a patient treated with atazanavir.

Of the recently approved antiretroviral protease inhibitors, atazanavir has become a popular medication for the treatment of HIV infection. The advantages of an atazanavir-based regimen include a favorable side effect profile, low impact on lipids, low pill burden, and daily dosing. These have made it a favorable choice for antiretroviral treatment. As more experience is gained with newer antiretroviral medications, additional side effects become apparent. Recent reports have highlighted occurrences of nephrolithiasis in patients using atazanavir-based regimens. The authors present a case of a patient who experienced nephrolithiasis while taking combination antiretroviral therapy that included atazanavir.
